To provide a technology of enabling dredging operations to be performed in a lower-powered manner with a high degree of efficiency without use of large-scale equipment.
This dredging conveyance system comprises: a dredging section 10 which performs dredging by utilizing a difference between a water level of a dam lake and that of the inside of a water-level difference making water tank 14; a conveyance section 40 for pumping up sediment water, from which refuse is removed by means of a refuse screen 14b in the water-level difference making water tank 14, by using a scouring pump 22, so as to convey the sediment water to a dam body D through a carrier pipe 24; a dam-body crossing section 30 which transfers the sediment water into a water receiving tank 34 by exceeding a difference of elevation between the water level in the water receiving tank 34 and the top section of the dam body D through the use of atmospheric pressure (natural energy) by means of the water receiving tank 34 installed outside the dam body D; and a downstream conveyance section 40 which discharges the sediment water to a low place from the water receiving tank 34.
